"The average person spends around six years of their lives dreaming. If we are able to become lucid and control our dreams, we can then use our dreaming time more productively," continues Dr Aspy.

"Lucid dreaming, where you know that you are dreaming while the dream is still happening, has many potential benefits. For example, it may be possible to use lucid dreaming for overcoming nightmares, treating phobias, creative problem solving, refining motor skills and even helping with rehabilitation from physical trauma."

Participants felt the effects of the vitamin strongly. "It seems as time went on my dreams were clearer and clearer and easier to remember. I also did not lose fragments as the day went on," commented one of the participants after completing the study while another said, "My dreams were more real, I couldn't wait to go to bed and dream!"
